Current Developments and Recent Applications of Accelerated Bridge Construction

Thursday, June 12, 2014 - 8:00am-12:00pm

Presented by: Michael Baker Jr., Inc., HDR Engineering Inc., Federal Highway Administration, Utah Department of Transportation

With approximately 25% of the nation's 600,000 bridges requiring rehabilitation, repair, or total replacement, Accelerated Bridge Construction (ABC) technologies offer a variety of cost-effective techniques to quickly repair or replace existing bridges while reducing impacts to mobility and safety. Through the Every Day Counts initiative, state highway agencies are working with the Federal Highway Administration (FHWA) to implement ABC technologies in typical bridge rehabilitations and replacements as a part of their standard business practices. This seminar will cover a variety of timely topics associated with the application of ABC techniques and provide attendees with an understanding of the advantages and implications of ABC techniques currently available to bridge designers, owners and constructors. Attendees will see presentations that demonstrate the successful use of ABC across a wide range of applications from the use of precast elements to full bridge prefabrication and bridge moves. Presentations will include:

  • The extensive use of large, precast elements on the $3.1B Tappan Zee Bridge Project to speed construction, improve safety, and provide a durable final product which meets the 100 year service life requirements (invited). 

  • An update on the Federal Highway Administration “Every Day Counts” program and current ABC initiatives

  • Development of a Slide - In Bridge Construction (SIBC) Manual for Utah DOT and FHWA

  • Owner’s Perspective on Effective ABC Use

Speakers: Michael Arens, P.E., S.E., Michael Baker Jr. Inc., Salt Lake City, UT; Mike LaViolette, P.E., HDR Engineering Inc., Omaha, NE; Ben Beerman, P.E., Federal Highway Administration, Washington, DC; Linda Kreuger, P.E., Michael Baker Jr. Inc., Madison, WI; Eliza Partington, Massachusetts Department of Transporatation, Boston, MA (Invited)

Load Rating of Complex Bridges

Thursday, June 12, 2014 - 1:00pm-5:00pm

Presented by: Michael Baker Jr., Inc.

This seminar will focus on tools and analysis methods available to engineers for the load rating of non-conventional and complex bridges.  The seminar will demonstrate strategies for load rating of complex structures through the discussion of a number of recently load-rated structures from a variety of different states, including but not limited to the following:

  • Cleveland Central Viaduct Bridge Deck Truss over the Cuyahoga River (OH)

  • Sherman Minton Trussed Tied Arch over the Ohio River (IN/KY)

  • Daniel Hoan Bridge Steel Tied Arch Main Spans (WI)

  • Hoan Bridge Concrete Box Girder Approaches (WI)

  • Fulton Road Post-Tensioned Concrete Deck Arch (OH)

  • Oklahoma DOT Post-Tensioned Segmental Box Girders

In addition, the seminar will introduce new functionality of the AASHTOWare Bridge Rating (“BrR” - formerly “Virtis”) software related to the load rating of non-conventional bridge types including steel curved/skewed bridges and trusses. BrR is currently under evaluation by the Pennsylvania Department of Transportation for acceptance as an approved load rating tool for statewide bridges.

Topics covered in this seminar will include the use of 2D and 3D finite element modeling, appropriate modeling techniques, and LRFR code checking.

Speakers: Dr. Francesco Russo, Ph.D., P.E., Michael Baker Jr. Inc., Philadelphia, PA; Daniel Baxter, P.E., S.E., Michael Baker Jr. Inc., Minneapolis, MN; Rachel Sharp, P.E., Michael Baker Jr. Inc., Moon Township, PA
